These esters are readily hydrolysed and yield the monoand di-alkylimalonic acids which, on heating, are readily decomposed, with evolution of carbon dioxide and the formation of monoand di-alkyl acetic acids.
The simplest aromatic monamine is aniline, and the simplest mixed amines are monoand di-methyl aniline.
The three series also differ when heated: the trimetallic salts, containing fixed bases are unaltered, whilst the monoand dimetallic salts yield metaand pyrophosphates respectively.
If the heating be with charcoal, the trimetallic salts of the alkalis and alkaline earths are unaltered, whilst the monoand di-salts give free phosphorus and a trimetallic salt.
Fittig (Ann., 1876, 180, p. 23) readily explains the formation of the monoand di-oximes of quinone and also that it readily combines with bromine.
Cyanogen iodide and iodine monoand tri-chloride effect similar decompositions with simultaneous liberation of iodine; sulphuric acid reacts slowly, forming nickel sulphate and liberating hydrogen and carbon monoxide.
It is also formed in the pancreatic fermentation of albumen, and, in small quantities, by passing the vapours of monoand dialkylanilines through a red-hot tube.
